 *
 *  Currently we only declare some charset's properties here
 *  (such as MIME names, etc.), it does not include real mapping.
 *
 *  There is a place marked "Add your new character sets HERE" in this file.
 *  Make up a character set and add it in the same
 *  style as the ISO_LATIN1 set below, giving it a unique name.
 *
 *  Add the name of the set to LYCharSets.
 *  Similarly add the appropriate information to the tables below:
 *  LYchar_set_names, LYCharSet_UC, LYlowest_eightbit.
 *  These 4 tables all MUST have the same order.
 *  (And this is the order you will see in Lynx Options Menu,
